Hereinafter, embodiments of the disclosure will be described in detail with reference to the accompanying drawings so that those skilled in the art to which the disclosure pertains may easily practice the disclosure.

FIG. 1 is a diagram illustrating an example display device according to various embodiments. A display device 100 may be implemented as television (TV), a smartphone, a tablet, and the like.

In this case, the display device 100 may play content. In this case, the content may include images and/or audio. Accordingly, the display device 100 may display the image on the display device 100 (e.g., on a display of the display device) and output the audio through the display device 100 (e.g., via a speaker of the display device).

The content may include content provided through an over-the-top (OTT) media service. Here, the OTT media service may refer, for example, to a service for streaming various contents through the Internet network. In this case, the content may be played through an OTT media service application installed on the display device 100. To this end, as an example, the display device 100 may receive content provided by each OTT media service provider from a first OTT media service server 200 and a second OTT media service server 300.

The content may include broadcast content provided through broadcast channels by providers of various broadcast services, such as terrestrial broadcast, cable broadcast, and satellite broadcast. To this end, the display device 100 may receive broadcast content from a broadcasting station 400 or the like.

The playback of the content being played through the display device 100 may be stopped.

Here, the stopping of playback may include a case in which the content displayed on the display device 100 is changed by the user changing the content being played to another (different) content. In addition, the stopping of playback may include a case in which the content displayed on the display device 100 is no longer displayed for reasons such as the user terminating watching of the content being played.

In this case, when the content whose playback is stopped is content provided through the OTT media service application, the user may continue to watch the stopped content by executing the OTT media service application again (e.g., re-executing the OTT media service). However, in this case, when the user does not clearly remember the corresponding OTT media service application, there may be an inconvenience of executing and checking OTT media service applications installed on the display device 100 until the corresponding OTT media service application is found.

Meanwhile, the content whose playback is stopped may be broadcast content. In that the broadcast content is content that is provided in real time through a broadcast channel, an inconvenience may arise in that the user needs to find a channel and a broadcast time on which the broadcast content whose playback is stopped is broadcasted again, and then watch the corresponding broadcast content again from a point of time when the playback is stopped.

Accordingly, the display device 100 according to various embodiments may, when the playback of content is stopped, store information on the content whose playback is stopped and information on the point of time when the playback is stopped, and, using the stored information, start playing the content again from the point of time at which the playback was stopped. As described above, according to various embodiments, the convenience of the user may be increased in that the user may easily continue to watch the content or broadcast content whose playback is stopped through the application or the broadcast channel.

FIG. 2 is a block diagram illustrating a configuration of an example display device according to various embodiments. A display 110 may display content. In addition, the display 110 may display a UI screen for an operation of the display device 100.

To this end, the display 110 may be implemented with various types of displays such as a liquid crystal display (LCD), a light emitting diode (LED), or an organic light emitting diode (OLED).

A memory 120 may store data for the operation of the display device 100. In particular, the memory 120 may store various pieces of information necessary to play the content whose playback is stopped from the point of time when the playback is stopped, and a detailed description thereof will be provided later.

In addition, one or more instructions regarding the display device 100 may be stored in the memory 120. The memory 120 may store an operating system (O/S) for driving the display device 100. The memory 120 may also store various software programs or applications for operating the display device 100 according to various embodiments. The memory 120 may include a semiconductor memory such as a volatile memory or a flash memory, or a magnetic storage medium such as a hard disk.

A processor 130 (e.g., including processing circuitry) may be electrically connected to the display 110 and the memory 120 to control an overall operation and function of the display device 100.

The processor 130 may include a central processing unit (CPU) or an application processor (AP), and may execute one or more software programs stored in the memory according to the one or more instructions stored in the memory 120 of the display device 100.

First, the processor 130 may control playing of content. For example, the content may be content provided through the OTT media service application.

In an embodiment, the processor 130 may display a UI screen for executing the OTT media service application stored in the memory 120. In addition, when a user command for selecting one of the OTT media service applications is input, the processor 130 may execute the selected OTT media service application and display an execution screen of the application on the display 110.

In an embodiment, the execution screen of the application may include information (e.g., the name of the content, a thumbnail image, etc.) on a plurality of contents provided through the OTT media service.

Accordingly, when a user command for selecting one content on the execution screen of the application is input, the processor 130 may transmit a command to a server providing the OTT media service for requesting streaming of the selected content. In an embodiment, the display device 100 may include a communication interface (not illustrated) (e.g., including communication circuitry) for communication with the server. In this case, the communication interface (not illustrated) may communicate with the server through a network using various communication methods such as Wi-Fi, 3G, LTE, and the like.

Accordingly, the processor 130 may play the content received from the server. In an embodiment, the content may include images and/or audio. That is, when the image and/or audio are received from the server, the processor 130 may display the image on the display 110 and output the audio through a speaker of the display device 100.

In an embodiment, when the playback of the plurality of contents played through the plurality of applications is stopped, the processor 130 may store, in the memory 120, information on the plurality of applications, information on the plurality of contents, and information on a playback time point at which playback is stopped.

In an embodiment, the stopping of the playback may include ending the content being played, ending an application that plays the content, or changing the content being played to another content. In an embodiment, when a user command for stopping playback is input, the processor 130 may identify that the playback of the content being played through the application is stopped. The user command may be input in various ways, such as, but not limited to, remote control operation, voice recognition, or a touch input to a button provided in the display device 100 or a touch screen included in the display 110.

In an embodiment, each of the plurality of applications may be an application that provides a service for streaming content stored in a server to the display device through an Internet network. That is, the application may be an application that provides the OTT media service.

In addition, information on the application may be information for identifying each of the plurality of applications stored in the memory 120. For example, the information on the application may include, but is not limited to, an application ID and/or a name of the application.

In addition, the information on the content may include, but is not limited to, a content ID, a content title, and/or a content image.

In an embodiment, the content ID is information for identifying each of the plurality of contents provided by the application, and may be assigned by a provider providing the OTT media service.

The information on the content title may include title and episode information of the content. The information on the content image may include URL information of a website that provides a thumbnail image file of the content or a thumbnail image of the content.

In an embodiment, the information on the playback time point at which the playback of the content is stopped may include information on the point of time when the playback of the content is stopped. For example, when a total length of the content is 2 hours and the playback is stopped at 1 hour 20 minutes, the playback time point at which the playback is stopped may include information on a point of time when the playback is currently stopped relative to a total length of the content, for example, (1:20:20/2:00:00) (=(point of time when playback is stopped/total length of content)).

In an embodiment, when the playback of the plurality of contents played through the plurality of applications is stopped, the processor 130 may acquire the information on the applications, the information on the contents, and the information on the playback time point at which the playback is stopped. The processor 130 may store, in the memory 120, the information on the applications, the information on the contents, and the information on the playback time point at which the playback is stopped.

In an embodiment, when the playback of the content being played through the OTT media service application is stopped, the processor 130 may store, in the memory 120, information on the OTT media service application, information on the content whose playback is stopped, and information on a playback time point at which playback is stopped. In this case, the corresponding information may be stored in a data set 121 (See FIG. 3 ) of the content whose playback is stopped of the memory 120.

For example, as illustrated in FIG. 3 , a plurality of contents may be played through a plurality of OTT media service applications 132.

In an embodiment, when playback of “a content” being played through an application A 132-1 is stopped, the processor 130 may acquire information on the application A, information on “the a content” and information on a playback time point at which the playback of “the a content” is stopped, and store the acquired information in the data set 121. When playback of “b content” being played through an application B 132-2 is stopped, the processor 130 may acquire information on the application B, information on “the b content”, and information on a playback time point at which the playback of “the b content” is stopped, and store the acquired information in the data set 121. When playback of “c content” being played through an application C 132-3 is stopped, the processor 130 may acquire information on the application C, information on “the c content” and information on a playback time point at which the playback of “the c content” is stopped, and store the acquired information in the data set 121.

According to various embodiments, when an application that provides a continuous content playback service is executed, the processor 130 may display, on the display 110, a user interface (UI) screen for playing the plurality of contents from a point of time when the playback is stopped using the information stored in the memory 120. In an embodiment, when a user command for selecting content is input through the UI screen, the processor 130 may display the content selected according to the user command on the display 110 from the point of time when the playback is stopped.

In an embodiment, the application that provides the continuous content playback service (hereinafter, a continuous play application) may refer, for example, to an application for providing recommended content. In this case, the recommended content may include content of a genre frequently watched by the user through the display device 100, content set by the user as a favorite, and the like. In this case, according to an embodiment, the recommended content may include the content whose playback is stopped.

In an embodiment, the processor 130 may display a UI screen for executing the continuous play application stored in the memory 120 on the display 110. In addition, when a user command for selecting the continuous play application is input, the processor 130 may execute the continuous play application.

When the continuous play application is executed, the processor 130 may generate a UI screen through the continuous play application using the information stored in the memory 120, and may display an execution screen of the application including the UI screen on the display 110.

Specifically, the processor 130 may display, on the display 110, a UI screen for playing a plurality of contents from a point of time when the playback is stopped based on information on the plurality of applications, information on the plurality of contents, and information on a playback time point when the playback is stopped. The UI screen may be a UI screen for displaying the content played in the application.

In an embodiment, as illustrated in FIG. 4A, when a continuous play application 131 is executed, the processor 130 may generate a UI screen based on information on a plurality of applications, information on a plurality of contents, and information on a playback time point when the playback is stopped of the data set 121 through the continuous play application, and may display the UI screen on the display 110.

In an embodiment, as illustrated in FIG. 4B, the data set 121 may include information on a name 421 of an application that played content whose playback is stopped, a content ID 422, a playback time point when the playback is stopped 423, a content title 424, and a content image 425.

Accordingly, as illustrated in FIG. 4C, a UI screen 430 displayed on the display 110 of the display device 100 by the processor 130 may include a graphic object indicating the name of the application, a thumbnail of the content whose playback is stopped in the application, and the point of time when the playback is stopped for each of the OTT media service applications 431, 432, 433, and 434 (e.g., a graphic object indicating the time when the playback is stopped relative to a total playback time). As shown in FIG. 4C, the point of time when the playback is stopped for particular content may be graphically represented in a progress bar 440 beneath the particular content. In an embodiment, the point of time may be represented numerically or both numerically and in a progress bar.

In an embodiment, when a user command for selecting one of the plurality of contents is input through the UI screen, the processor 130 may execute an application in which the selected content among the plurality of applications is played. In addition, the processor 130 may play the selected content from the point of time when the playback is stopped through the executed application using information on the selected content and information on a playback time point when the playback of the selected content is stopped.

For example, when a user command for selecting content is input through the UI screen, the processor 130 may identify the content selected according to the user command, and execute an application in which the content is played. In addition, the processor 130 may provide information on a content ID of the selected content and a playback time point when the playback of the selected content is stopped to the executed application.

In an embodiment, the application, that is, the OTT media service application, may access a deep link for playing the content from the point of time when the playback is stopped using the information on the content ID and the playback time point when the playback is stopped.

Here, the deep link may refer, for example, to an address or value having a function of executing a specific application or moving to a specific screen within the specific application.

In an embodiment, each of the plurality of applications may be pre-programmed to access a deep link for playing specific content from a point of time when playback of the content is stopped using information on the specific content ID and a playback time point when the playback of the specific content is stopped.

Accordingly, the application may stream and play the content from the point of time when the playback is stopped through the deep link.

For example, as illustrated in FIG. 5 , the user may select a thumbnail 510 of the content played in the application A among the thumbnails of the plurality of contents whose playback is stopped on the UI screen displayed on the display 110 of the display device 100.

In an embodiment, the processor 130 may execute the application A and play content 520 through the application A from the point of time when the playback is stopped.

As described above, according to an embodiment, the display device 100 may display information on the plurality of contents whose playback is stopped in the plurality of applications through one application. Accordingly, the user may easily detect what content he/she has stopped watching, how much he/she has watched the content, and through which application he/she has watched the content, and may receive a continuous play function.

There may be cases in which the content whose playback is stopped may not be continuously played through the application, due to reasons such as deletion of the application that played the content whose playback is stopped, or no longer providing the playback service of the content whose playback is stopped.

According to an embodiment, when the content whose playback is stopped in the plurality of applications is provided through a broadcast channel, the processor 130 may receive the corresponding content from the point of time when the playback is stopped and display the corresponding content through the broadcast channel from the point of time when the playback is stopped.

In an embodiment, the memory 120 may store information on a broadcast schedule. Here, the information on the broadcast schedule may include information on a broadcast time of broadcast contents provided through a plurality of channels. That is, the information on the broadcast schedule may, for example, be electronic program guide (EPG) information, and may be provided by a broadcasting station or the like. In this case, the corresponding information may be stored in a data set 122 of a broadcast schedule of the memory 120.

In addition, the processor 130 may identify a channel that provides content after the point of time when playback is stopped among a plurality of channels based on information on broadcast schedules of the plurality of channels, information on a plurality of contents, and information on a playback time point at which the playback is stopped, and may display a UI screen for displaying content provided from the identified channel on the display 110.

For example, as illustrated in FIG. 6A, when the continuous play application 131 is executed, the processor 130 may generate a UI screen based on the information on the plurality of contents and the information on the playback time point when the playback is stopped of the data set 121, and the information on the broadcast schedule of the plurality of channels of the data set 122 through the continuous play application, and may display the UI screen on the display 110.

The processor 130 may provide the same content as the content whose playback is stopped based on a point of time when an application providing the continuous content playback service is executed, based on the information on the broadcast schedules of the plurality of channels, the information on the plurality of contents, and the information on the playback time point when the playback is stopped. The processor 130 may identify a broadcast channel in which a difference between a current playback time point of the broadcast content and the playback time point of the content whose playback is stopped is less than a preset time.

In an embodiment, the processor 130 may identify the identified broadcast channel as a channel providing content after the point of time when the playback is stopped.

For example, as illustrated in FIG. 6B, the data set 121 of the content whose playback is stopped and the data set 122 of the broadcast schedule are stored in the memory 120. In this case, the data set 122 of the broadcast schedule may include information on a name 621 of a channel, a broadcast time 622, and a name 623 of broadcast content.

In an embodiment, at the point of time at which the continuous play application is executed, content 424-1 of the data set 121 may be the same as the broadcast content 623-1 being broadcast on channel 003 of the data set 122 as an episode Y-1, and content 424-2 of the data set 121 may the same as the broadcast content 623-2 being broadcast on channel 004 of the data set 122 as an episode Y-2.

In an embodiment, at the point of time at which the continuous play application is executed, the playback time point when the playback of the episode Y-1 of the data set 121 is stopped is (1:05:50/1:30:00), and the current playback time point of the episode Y-1 being broadcast on channel 003 of the data set 122 is (1:03:30/1:30:00), and a difference between the two time points is 0:02:20. In addition, when the preset time is set to 0:05:30, the difference between the two time points is less than the preset time, and therefore, the processor 130 may identify the channel 003 of the data set 122 as a channel providing the episode Y-1 after the point of time when the playback is stopped.

On the other hand, the playback time point when the playback of the episode Y-2 of the data set 121 is stopped is (01:25:05/1:30:00), and the current playback time point of the episode Y-2 being broadcast on channel 004 of the data set 122 is (00:30:10/1:30:00), and a difference between the two time points may be 0:54:55. In addition, when the preset time is set to 0:05:30, the difference between the two time points is the preset time or more, and therefore, the processor 130 does not identify the channel 004 of the data set 122 as a channel providing the episode Y-2 after the point of time when the playback is stopped.

In the above example, the preset time is 0:05:30, but the preset time is not limited thereto. In addition, the preset time may be may be changed according to a user's command.

In an embodiment, the processor 130 may display a UI screen for displaying content provided from the identified channel on the display 110.

For example, as illustrated in FIG. 6C, a UI screen 630 displayed on the display 110 of the display device 100 by the processor 130 may include the name of the channel, a thumbnail of the content whose playback is stopped in the application, and a graphic object indicating of the point of time (e.g., a progress bar) when the playback is stopped for each of the identified channels 631, 632, and 633.

In an embodiment, when a user command for selecting content is input through the UI screen, the processor 130 may display the content provided through the identified channel on the display 110.

Specifically, the processor 130 may identify the content selected by the user command input through the UI screen. In addition, the processor 130 may receive the selected content through a broadcast receiver (not illustrated) through the channel identified as providing the selected content.

The broadcast receiver (not illustrated) is a component that may receive contents transmitted through a plurality of channels from a broadcasting station. The broadcast receiver (not illustrated) may include a tuner (not illustrated), a demodulator (not illustrated), and a decoder (not illustrated).

In an embodiment, the processor 130 may receive content provided through the identified channel using the broadcast receiver (not illustrated). In addition, the processor 130 may display the content received through the broadcast receiver (not illustrated) on the display 110.

For example, as illustrated in FIG. 7 , the user may select a thumbnail 710 of the content provided from the channel 003 among the thumbnails of the plurality of contents whose playback is stopped on the UI screen displayed on the display 110 of the display device 100.

In an embodiment, the processor 130 may display content 720 provided from the channel 003 on the display 110.

As described above, according to an embodiment, through the display device 100, the plurality of contents whose playback is stopped in the application may be continuously watched on the broadcast channel in real time. Accordingly, even when the user may not continue to watch the content whose playback is stopped in the application, the user may continue to watch the content through the broadcast channel.

In the above-described example, it has been described that the UI screen includes only the UI screen for displaying the content played in the application or the UI screen for displaying the content provided from the identified channel. In addition, according to an embodiment, the UI screen may also include both the UI screen for displaying the content played in the application and the UI screen for displaying the content provided from the identified channel.

That is, when the continuous play application is executed, the processor 130 may display the UI screen for displaying the content played in the application and the UI screen for displaying the content provided from the identified channel on the display 110, based on the data set 121 of the content whose playback is stopped and the data set 122 of the broadcast schedule.

For example, as illustrated in FIG. 8 , the UI screen may include a name of an application, a thumbnail of content whose playback is stopped in an application, and a graphic object indicating of a point of time (e.g., a progress bar) when the playback is stopped for each of the OTT media service applications 811 and 812. In addition, the UI screen may include a name of a channel, a thumbnail of content whose playback is stopped in an application, and a graphic object indicating a point of time (e.g., a progress bar) when the playback is stopped for each of the identified channels 821 and 822.

When a user command for selecting content is input through the UI screen, the processor 130 may play the content selected from the point of time when the playback is stopped through the application, or display the content provided through the identified channel on the display 110.

The above-described embodiments relate to providing the continuous play function of the content whose playback is stopped in the application. However, according to an embodiment, a continuous play function of broadcast content whose display is stopped may also be provided, which will be described in detail below.

In an embodiment, the processor 130 may display broadcast content on the display 110. That is, the processor 130 may display an image of the broadcast content on the display 110. In addition, the processor 130 may output audio of the broadcast content through a speaker of the display device 100.

In an embodiment, the display device 100 may receive the broadcast content through a broadcast receiver (not illustrated) or may be connected to a set-top box and the like to receive terrestrial broadcast, cable broadcast, satellite broadcast, and the like.

Accordingly, when the broadcast content is received, the processor 130 may display the image on the display 110 and output the audio through the speaker of the display device 100.

When a user command for stopping the display of broadcast content is input while the broadcast content provided through the channel is displayed on the display 110, the processor 130 may store information on the broadcast content and information on a watching time of the broadcast content in the memory 120.

The user command for stopping the display of the broadcast content may include various commands for preventing the broadcast content being played from being displayed on the display 110 such as, but not limited to, a command for changing a channel through which broadcast content is provided and a command for turning off the power of the display device 100. The user command may be input in various ways, such as remote control operation, voice recognition, and a touch input to a button provided in the display device 100 or a touch screen included in the display 110.

In an embodiment, when the user command for stopping the display of broadcast content is input, the processor 130 may store the information on the broadcast content and the information on the watching time of the broadcast content in the memory 120.

Here, the information on the broadcast content may include a title of broadcast content, an image of broadcast content, and the like.

Information on the title of broadcast content may include information on the name and episode of the broadcast content. The information on the image of the broadcast content may include URL information of a website that provides a thumbnail image file of the broadcast content or a thumbnail image of the broadcast content.

In an embodiment, the information on the watching time of the broadcast content may include information on the point of time when the display of the broadcast content is stopped. For example, when a total length of the broadcast content is 1 hour and the display thereof is stopped at 30 minutes 20 seconds, the information on the watching time of the broadcast content may include information on a point of time when the display is currently stopped relative to the total length of the broadcast content, for example, (30:20/1:00:00) (=(time when display is stopped/total broadcast time of broadcast content)).

Such information may be acquired from an automatic content recognition (ACR) service server (not illustrated) using ACR technology.

Here, the ACR technology refers, for example, to a technology for extracting image data or audio data included in content, and comparing the extracted data with pre-stored data to identify what kind of content the content is, in order to identify what kind of content the image content is. In this case, the pre-stored data may include all or part of an image frame including specific content and all or part of the audio data including the specific content.

In an embodiment, the processor 130 may transmit the image data displayed on the display 110 and the audio data output through the speaker of the display device 100 to an ACR service server (not illustrated) through a communication interface (not illustrated). In this case, the processor 130 may transmit the image and audio data to the ACR service server (not illustrated) at preset time intervals.

In an embodiment, the display device 100 may include a communication interface (not illustrated) for communication with the ACR service server (not illustrated). In this case, the communication interface (not illustrated) may communicate with the ACR service server through a network using various communication methods such as Wi-Fi, 3G, LTE, and the like.

In an embodiment, the ACR service server (not illustrated) may receive data from the display device 100, analyze the received data through the ACR technology to identify broadcast content displayed on the display device 100, and transmit the name, episode, image, and the like of the identified broadcast content to the display device 100.

The ACR service server (not illustrated) may also acquire information on the watching time of the broadcast content, and transmit the acquired information on the watching time of the broadcast content to the display device 100.

Specifically, the ACR service server (not illustrated) may identify the broadcast content displayed on the display 110 at preset time intervals, and identify a point of time when the display of the identified broadcast content is stopped on the display 110. In addition, the ACR service server (not illustrated) may acquire information on the watching time of the broadcast content based on the identified point of time at which the display is stopped and the information on the broadcast schedule of the broadcast content.

For example, the broadcast content displayed on the display 110 may be identified as A at a specific point of time (e.g., 13:29), and the broadcast content displayed on the display 110 may then be identified as B at a point of time (e.g., 13:30) after a predetermined time interval from the specific point in time.

In this case, the ACR service server (not illustrated) may identify that the display of the broadcast content A is stopped on the display 110 at 13:30. In addition, the ACR service server (not illustrated) may identify the total broadcast time of the broadcast content A based on the information on the broadcast schedule stored in the ACR service server (not illustrated). In this case, as an example, when the total broadcast time of the broadcast content A is from 13:00 to 14:00, the ACR service server (not illustrated) may identify that the display of the broadcast content A on the display 110 is stopped at a point of time when 30 minutes is elapsed since the broadcast content A starts broadcasting.

In an embodiment, the ACR service server (not illustrated) may transmit the acquired information on the watching time of the broadcast content to the display device 100.

In the above-described example, the ACR service server (not illustrated) has been described as using ACR technology to identify the broadcast content displayed on the display 110, but this is an example, and the processor 130 may identify the broadcast content displayed on the display 110 using ACR technology, and also acquire the information on the identified broadcast content and the information on the watching time of the broadcast content. In this case, the processor 130 may, for example, acquire the corresponding information using the ACR technology through an ACR service application.

In addition, the processor 130 may store the acquired information on the broadcast content and information on the watching time of the broadcast content in the memory 120. In this case, the corresponding information may be stored in a data set 123 of broadcast content whose playback is stopped in the memory 120.

For example, as illustrated in FIG. 9 , the processor 130 may acquire information on “broadcast content d” and information on a watching time of “the broadcast content d” from the ACR service server 500 and store the acquired information in the data set 123. In addition, the processor 130 may acquire information on “broadcast content e” and information on a watching time of “the broadcast content e” through the ACR service application 133 and store the acquired information in the data set 123.

In an embodiment, when the application 131 that provides the continuous content playback service is executed, the processor 130 may display, on the display 110, a UI screen for providing the broadcast content from the point of time when the playback is stopped based on information on the broadcast content and information on a playback time point when the playback of the broadcast content is stopped.

Specifically, when the application 131 that provides the continuous content playback service is executed, the processor 130 may identify an application providing the broadcast content among the plurality of applications based on information on content provided from each of the plurality of applications and information on the broadcast content.

In an embodiment, the memory 120 may store the information on the content provided from each of the plurality of applications. Here, the information on the content provided from each of the plurality of applications may include information on the content title and the content ID provided from each of the plurality of applications. In addition, the information on the content provided from each of the plurality of applications may be provided from a server that provides the OTT media service. In this case, the corresponding information may be stored in a data set 124 of content provided from an application of the memory 120.

For example, as illustrated in FIG. 10A, when the continuous play application 131 is executed, the processor 130 may generate a UI screen based on information on a plurality of broadcast contents of the data set 123 and information on content provided from each of a plurality of applications of the data set 124 through the continuous play application, and may display the UI screen on the display 110.

In an embodiment, the processor 130 may identify an application in which the same content as the broadcast content whose playback is stopped is in a content providing list based on the information on the content provided from each of the plurality of applications and the information on the broadcast content. In addition, the processor 130 may identify a content ID of the broadcast content whose playback is stopped.

For example, as illustrated in FIG. 10B, the data set 123 of the broadcast content whose playback is stopped and the data set 124 of the content provided from the application are stored in the memory 120. In this case, the data set 124 of the content provided by the application may include information on an application name 1021, a content name 1022, and a content ID.

In an embodiment, broadcast content 1031-1 of the data set 123 may be the same as the content 1022-1 provided from an application A of the data set 124 as an episode Q-1, and broadcast content 1031-2 of the data set 123 may the same as the content 1022-2 provided from an application C as an episode R.

In this case, the processor 130 may identify the application A as an application providing the broadcast content Q-1. In addition, the processor 130 may identify an ID of the content Q-1 provided from the application A of the data set 124 as an ID of the broadcast content Q-1.

In addition, the processor 130 may identify the application C as an application providing the broadcast content R. In addition, the processor 130 may identify an ID of the content R provided from the application C of the data set 124 as an ID of the broadcast content R.

In an embodiment, the processor 130 may display a UI screen including information on the broadcast content provided from the identified application on the display 110.

The UI screen including the information on the broadcast content provided from the identified application is the same as the UI screen for displaying the content played in the application described with reference to FIG. 4C, and a detailed description thereof will not be repeated here.

In an embodiment, when a user command for selecting broadcast content is input through the UI screen, the processor 130 may execute the identified application. In addition, the processor 130 may play the broadcast content after the watching time through the executed application using the information on the watching time of the broadcast content.

For example, when the user command for selecting the broadcast content is input through the UI screen, the processor 130 may identify the broadcast content selected according to the user command and execute the application identified as providing the broadcast content. In addition, the processor 130 may provide information on an ID of the selected broadcast content and a point of time when the watching of the selected broadcast content is stopped to the executed application.

In an embodiment, the executed application may stream and play the broadcast content from the point of time when the display is stopped through a deep link. A method of streaming and playing the broadcast content through a deep link by the application is the same as the method of streaming and playing the content through the deep link by the application described above, and a detailed description thereof will not be repeated here. As described above, according to an embodiment, the display device 100 may continuously play the broadcast content whose playback is stopped through the application. Accordingly, the user may continue to watch the broadcast content whose playback is stopped when he/she wants, regardless of the broadcast time of the broadcast content whose playback is stopped.

There may be cases in which the broadcast content may not be played through the application due to reasons such as the broadcast content whose display is stopped is not in the content list provided by the application.

Accordingly, according to an embodiment, when the broadcast content whose watching is stopped is provided through a broadcast channel, the processor 130 may receive and display the broadcast content whose watching is stopped through the broadcast channel.

When the application that provides the continuous content playback service is executed, the processor 130 may identify a channel providing the broadcast content after the watching time among the plurality of channels based on information on broadcast schedules of the plurality of channels, information on the broadcast content, and information on a playback time point when the playback of the broadcast content is stopped.

In an embodiment, the processor 130 may identify the channel that provides the content after the watching time among the plurality of channels based on the information on the broadcast schedules of the plurality of channels, the information on the broadcast content, and the information on the watching time of the broadcast content, and may display a UI screen including information broadcast content provided from the identified channel on the display 110.

For example, as illustrated in FIG. 11 , when the continuous play application 131 is executed, the processor 130 may generate a UI screen based on information on the broadcast schedules of the plurality of channels of the data set 122 and information on the broadcast content of the data set 123, and may display the UI screen on the display 110.

In an embodiment, the processor 130 may provide the same broadcast content as the broadcast content whose display is stopped based on a point of time when the application providing the continuous content playback service is executed, based on the information on the broadcast schedules of the plurality of channels, the information on the broadcast content, and the information on the watching time of the broadcast content, and may identify a broadcast channel in which a difference between a current playback time point of the broadcast content and a display stop time point of the broadcast content whose display is stopped is less than a preset time.

In addition, the processor 130 may identify the identified channel as a channel providing the broadcast content after the watching time.

A method of identifying the channel providing the broadcast content after the watching time is the same as the method of identifying the channel providing the content after the point of time when the playback is stopped with reference to FIG. 6B, and a detailed description thereof will not be repeated here.

In addition, the processor 130 may display a UI screen including information on the broadcast content provided from the identified channel on the display 110.

In addition, when a user command for selecting broadcast content is input through the UI screen, the processor 130 may display broadcast content provided through the identified channel on the display 110.

A method in which the processor 130 displays the UI screen including the information on the broadcast content provided from the identified channel on the display 110, and a method in which the processor 130 displays the broadcast content provided through the identified channel on the display 110 are the same as the method of displaying the UI screen including the identified content on the display and the method of displaying the content provided through the identified channel on the display 110 described above with reference to FIGS. 6C and 7 , and a detailed description thereof will not be repeated here.

As described above, according to an embodiment, the display device 100 may identify a channel that is broadcasting the broadcast content whose playback is stopped, and may continuously play the broadcast content whose playback is stopped on the identified channel. Accordingly, the user may continue to watch the broadcast content from the point of time when the playback is stopped without directly finding the broadcast schedule.

In an above-described example embodiment, it has been described that the processor 130 displays, on the display 110, the UI screen for playing the content from the point of time when the playback is stopped based on the data set 121 of the content whose playback is stopped, or displays, on the display 110, the UI screen for providing the broadcast content after the watching time based on the data set 123 of the broadcast content whose playback is stopped, but this is only an example. That is, the processor 130 may also display, on the display 110, the UI screen for playing the content from the point of time when the playback is stopped and the UI screen for providing the broadcast content after the watching time based on the data set 121 and the data set 123.

In an embodiment, as illustrated in FIG. 12 , when the continuous play application 131 is executed, the processor 130 may generate the UI screen for playing the content from the point of time when the playback is stopped and the UI screen for providing the broadcast content after the watching time based on a combination of the data set 121 of the content whose playback is stopped, the data set 122 of the broadcast schedule, the data set 123 of the broadcast content whose playback is stopped, and the data set 124 of the content provided from the application through the continuous play application, and may display the UI screens on the display 110.

A method of the generating and displaying the UI screen for playing the content from the point of time when the playback is stopped and the UI screen for providing the broadcast content after the watching time has been described above, and thus, a detailed description thereof will not be repeated here.

In an embodiment, the display device 100 may display, on the display 110, the UI screen for playing the content from the point of time when the playback is stopped or the UI screen for providing the broadcast content after the watching time based on information received from a server (not illustrated).

Here, the server (not illustrated) may store information on content and broadcast content watched on at least one display device linked to a user account, and may provide information on recommended content to at least one display device linked to the user account based on the stored information.

In an embodiment, the user of the display device 100 may link the display device 100 with the server (not illustrated). Specifically, the user of the display device 100 may link the display device 100 with the server (not illustrated) by registering his or her account in the display device 100. In this case, the processor 130 may communicate with the server (not illustrated) through a communication interface.

Accordingly, the processor 130 may transmit various pieces of information about the display device 100 to the server (not illustrated) through the communication interface.

For example, when the playback of the plurality of contents played through the plurality of applications is stopped, the processor 130 may transmit information on the plurality of applications, information on the plurality of contents, and information on a playback time point at which playback is stopped to the server (not illustrated) through the communication interface (not illustrated).

In an embodiment, when a user command for stopping the display of broadcast content is input while the broadcast content provided through the channel is displayed on the display 110, the processor 130 may transmit information on the broadcast content and information on a watching time of the broadcast content to the server (not illustrated) through the communication interface (not illustrated).

In an embodiment, when the application that provides the continuous content playback service is executed on the display device 100, the server (not illustrated) may transmit information for generating the UI screen for playing the content from the point of time when the playback is stopped or the UI screen for providing the broadcast content after the watching time based on the received information, the information on the broadcast schedules of the plurality of channels, and the information on the content provided from each of the plurality of applications to the display device 100. In this case, the information on the broadcast schedules of the plurality of channels and the information on the content provided from each of the plurality of applications may be information previously stored in the server (not illustrated) or information received from the display device 100.

In an embodiment, the processor 130 may generate a UI screen for playing the content from the point of time when the playback is stopped and a UI screen for providing the broadcast content after the watching time based on the received information, and may display the UI screens on the display 110.

In an embodiment, when a user command for selecting one of the plurality of contents or broadcast contents is input through the UI screen, the processor 130 may provide the selected content or broadcast content through an application or through a channel.

As described above, because the display device 100 according to an embodiment may provide a continuous content playback service based on the information received from a user's account server, the user of the display device 100 may continue to watch content or broadcast content that has stopped watching on another display device on the display device 100.

FIG. 13 is a flowchart illustrating an example controlling method of a display device according to various embodiments.

First, when playback of a plurality of contents played through a plurality of applications is stopped, information on the plurality of applications, information on the plurality of contents, and information on a playback time point at which the playback is stopped are stored in a memory of a display device (S1310).

In this case, each of the plurality of applications may be an application that provides a service for streaming content stored in a server to the display device through an Internet network.

Meanwhile, in step S1310, when a user command for stopping a display of broadcast content is input while the broadcast content provided through a channel is displayed, information on the broadcast content and information on a watching time of the broadcast content may be stored in the memory.

In an embodiment, when the application that provides the continuous content playback service is executed, a user interface (UI) screen for playing the plurality of contents from a point of time when the playback is stopped using the information stored in the memory is displayed (S1320).

In step S1320, when the application that provides the continuous content playback service is executed, a UI screen for providing broadcast content after a watching time based on the information on the broadcast content and the information on the watching time of the broadcast content may be displayed.

In this case, step S1320 includes identifying an application providing the broadcast content among the plurality of applications based on the information on the content provided from each of the plurality of applications and the information on the broadcast content when the application that provides continuous content playback service is executed, and displaying a UI screen including information on the broadcast content provided from the identified application. The controlling method may include executing the identified application and playing the broadcast content after the watching time through the executed application using the information on the watching time of the broadcast content, when a user command for selecting the broadcast content is input the UI screen.

In addition, step S1320 includes identifying a channel providing broadcast content after a watching time among a plurality of channels based on information on broadcast schedules of the plurality of channels, information on the broadcast content, and information on the watch time of the broadcast content when the application that provides continuous content playback service is executed, and displaying a UI screen including information on the broadcast content provided from the identified channel, and the controlling method may include displaying the broadcast content provided through the identified channel when a user command for selecting the broadcast content is input the UI screen.

Meanwhile, step S1320 may include identifying a channel that provides content after a point of time when playback is stopped among a plurality of channels based on the information on the broadcast schedules of the plurality of channels, the information on the plurality of contents, and the information on the playback time point at which the playback is stopped, and displaying a UI screen for displaying content provided from the identified channel.

In this case, step S1320 may include displaying a UI screen including information on the identified channel, and the controlling method may include displaying content provided through the identified channel when a user command for selecting the content is input through the UI screen.

A method of displaying a UI screen and a method of playing the content whose playback is stopped or displaying the broadcast content have been described above. Accordingly, the convenience of the user may be increased in that the user may easily continue to watch the content or broadcast content whose playback is stopped through the application or the broadcast channel.

FIG. 14 is a block diagram illustrating a detailed configuration of an example display device according to various embodiments.

Referring to FIG. 14 , the display device 100 may include a display 110, a memory 120, a communication interface 140, a broadcast receiver 150, a user inputter 160, a microphone 170, and a speaker 180. The components of display device 100 illustrated in FIG. 14 are only examples, and at least some of the components may be omitted or other components may be added according to various embodiments.

The display 110, the memory 120, and the processor 130 have been described with reference to FIGS. 1 to 13 , and thus, a detailed description of overlapping parts will not be repeated here.

The communication interface 140 (e.g., including communication circuitry) is a component for performing communication with external devices. The processor 130 may transmit various data to the external device through the communication interface 140 and receive various data from the external device.

For example, the communication interface 140 may communicate with various external devices through a wireless communication method such as Bluetooth (BT), Bluetooth low energy (BLE), wireless fidelity (WI-FI), and Zigbee, or infrared (IR) communication method. The communication interface 140 may be mounted on the processor 130, and may also be included in the display device 100 as a component separate from the processor 130.

The processor 130 may receive information on content stored in the external device through the communication interface 140. In addition, the processor 130 may play the content stored in the external device through the display 110 or the speaker 180 based on the received information.

The broadcast receiver 150 is a component that may receive a broadcast signal from a broadcasting station 400. For example, the processor 130 may receive the broadcast signal through the broadcast receiver 150 and play content provided through a broadcast channel through the display 110 or the speaker 180.

The user inputter 160 (e.g., including input circuitry) is a component for receiving various user commands. For example, the user inputter 160 may include a touch panel and the like, and may also include a remote control signal receiver to receive various user commands from a remote control for controlling the display device 100.

In this case, the processor 130 may control other components to execute various functions according to the user command input to the user inputter 160. For example, the processor 130 may execute an application that provides the continuous content playback service based on a command executed by the application that provides the continuous content playback service input through the user inputter 160.

The processor 130 may play selected content through an application or display the selected content on the display 110 through a channel based on a command for selecting content or broadcast content displayed on a UI screen which is input to the user inputter 160.

The microphone 170 may receive a voice. Here, the voice may include a user command for controlling an operation of the display device 100.
